# --description--

Define a function `verify_card_number` with a parameter `card_number`, and use the `pass` keyword to make the function do nothing.

# --hints--

You should have a function called `verify_card_number` with a parameter called `card_number`.

```js
({
    test: () => {
        const transformedCode = code.replace(/\r/g, "");
        const verify_card_number = __helpers.python.getDef("\n" + transformedCode, "verify_card_number");
        assert.exists(verify_card_number);
        const { function_parameters } = verify_card_number;
        assert.equal(function_parameters.trim(), "card_number");
    }
})
```

You should use the `pass` keyword in the body of the `verify_card_number` function.

```js
({
    test: () => {
        const transformedCode = code.replace(/\r/g, "");
        const verify_card_number = __helpers.python.getDef("\n" + transformedCode, "verify_card_number");
        assert.exists(verify_card_number);
        const { function_body } = verify_card_number;
        assert.match(function_body, / +pass/);
    }
})
```

    translated_card_number = card_number.translate(card_translation)
